Brought my Fisher F70 to a trash infested park built in the 1950's. There are bottle-caps, screw caps, old and new style pulltabs and other small metal trash items all over the park.
I concentrated on the area between the parking lot and the back of the baseball field.
I was gridding small sections, listening for every possible high toned coin target (solid tone scanned back-and-forth) overlapping my swings and going slow.
The F70 going slow got in between many trash items (dug over 20 because they were in the hole on a high toned sound) and located 49 clad coins
not real deep, 3-6 inches... but they had been missed because of all the trash in the park.
Pulled an old lady from her grave and brought her back to life...
She is quite pretty for being 102..........and if you are wondering........yes I took her home !!!!
